Figure 2-4. Example Design/Evaluation Earthquake Ground Motion

Response Spectrum

For systems and components, seismic design forces are accounted as per

the IBC 2000 provisions.

If a recent site-specific seismic hazard assessment is available, it can be

used subject to limitations imposed in the IBC 2000. For evaluation of

SSCs using site specific hazard analysis, the design shall be based on 5%

critical damping as recommended by the IBC 2000. Final earthquake loads

are subject to approval by DOE.

For structures, response modification coefficients, R, and for systems and

components RP are given in IBC 2000

Combine responses from various loadings (DNS and DSI) to evaluate

demand, DTI, by code specified load combination rules (e.g., load factors

for ultimate strength design or applicable load factors for allowable stress

design).
